Circuits and low pass filters

[QUOTE="Monsu, post: 341134, member: 16201"] [B]You are given a low pass filter of 50nF and a resistor of 100 KOhm. a) Draw the circuit diagram; b) Calculate the 3dB frequency; c) Calculate the impedance of the series circuit of R and C and draw it in the complex plane at about 2 decades around the 3dB point and at the 3dB point. d) Draw the circuit diagram for a high pass filter with same components. [/B] I am asked to calculate the 3db freq, right? is this the right formula f = 1 / (2piRC) ? and afterwards calc the impedance z = R + jXc where Xc = 1 / (2pifC) ? and then getting the decades, say our freq was 31.8Hz , 2 decades below would b 0.318? 2 decades above would b 3180? then we should use those values of f to determine the Xc at those frequencies, and then find z at each of these frequencies? then we plot a graph showing all the z's? pls smne help me coz I'm totally confused! thanks in advance! :smile: [/QUOTE]
